This is the largest tire that can clear 99% of articulated movement. Even though you raise your truck, your fender well opening size doesn't change, so when you stuff your tire under compression, ^^^above are the largest tires that will clear.

If you do some super minor trimming, seriously, like 15 min with a cut off wheel on your cab mounts and a welder to close off what you cut, you can stuff a 285 tire.
